So I'm trying to move my Queen, (who's currently still at her starting point) diagonally across a clear path, to take my opponents Bishop. It's a clear, simple move to me, but when I click on "submit move" the page reloads and my pieces are back where they were before I made the move? Also, the squares of my Queen and the opponents Bishop are pink which to me seems to signify that I can't make that move, although to my understanding, it's an allowable one... Could it be a glich on the website? Or maybe not compatible with my Mac OSX program? I just started a game for the first time a couple weeks ago and have made several moves already that have worked fine... I just don't know what I'm missing here!
